Mourning Dove (Chick)

I discovered this mourning dove nest a few days ago in my neighbor's tree. I think there are only two chicks, and I'm pretty sure both photos are of the same one. Today I went by it and they were both out of the nest on the branch, but when I came back later the parents were there and they were back in the nest. If you look in the first picture it has one eye open and one eye closed!
